This is already a very unusual World Cup, but it is about to get even more unusual on Tuesday when Stadium 974, a temporary venue, hosts its first tournament match.
Mexico take on Poland in a Group C fixture at the eye-catching ground at 4pm GMT, and the stadium is sure to be a talking point for fans.
The 40,000 seater venue, initially known at the Ras Abu Aboud Stadium, was opened in November last year, and is the first and so far only temporary stadium in World Cup history.
